Fact Check How Much Water Does Solar Power Really Use?KCET
May 06, 2021 · Coal-fired power plants use up 1,100 gallons of water for each megawatt-hour of power produced. (A megawatt-hour is about what a typical California would consume in six or seven weeks.) Nuclear and natural-gas-fired power plants use water 800 and 300 gallons for the same amount of power, respectively.
